1 0 all whom it may camera Be it known that I, JERRY H. Wonsnn, a theUnited States, residing at l lurelm, u j State of ivaslnngton, havenvcnted certain new and useful Improvements in bandtion. i j l i Thisinventiou relates to an improvement in. sand-boxes and has torits objectto pro (inst from entering the journaled portion of a hub and axle fromthe inner end thereof, and to further provide a means for attachingwheels an axle, as more particularly used on farm mp len cnts, in suchananner that no \d rt may enter and cause undu friction and attritihn.

With this and othcr objec s in view reference is had to the iceompanyingd rings, in which--- i JCigure 1 is a sectional elevation showing thepreter qed form of my inventionfand its application; j I hig/2 is asectional elevation ofa mod fication; i

The present hub 2 has an interior sleeve 41 interposed between the axle1 and the hub 2 which acts as a journal box for the hub, and which isrigidly attached to the hub by the bolt 5 joining the two together. Onthe inner end of the sleeve is a peripheral flange 6 about which aclamping device (not shown) is fastened, being held rigid to the axleand revo'lubly engaging the flange G of the sleeve 4 for the purpose 01:revolubly attaching the wheel to the axle.

Many kinds of cl amping devices used for this nirpose and many of the,deyices are termed am d-boxes, in common parlance meanlng a boxdesigned to prevent sand or other ab "asive from entering between twosurfaces operating at mn'ia ce, but which, in fact, and from the verynati re of their design, permit entrance of, and retain the sang or grt, cans ng i;

l ction a n d attrition to the two SIlI ILCQS. l

Inmy invention I provide a cylindrical sand-box 7 having an upperchanheled semicylindricalsectien S, a lower channel cyliiit lr calsection 9 (the two sect ,ing a cylinder) having in tlc liotoii or lowerportion preferably an oiiice it) to permit egress or any grit which mayenter the joint between the sand-box and the sleeve as at the point 11,before it has had opportunity to work its way between the axle 1 and thesleeve 4L, a space being left hetwecn thecurvedperipheral flange bandthe chanal part of the sand-box, 8 "and 9 rcspecti ily, thaltthemovement of the grit toward the bottom, and thus the orifice 10 may iiotbe, in' peded. The finer particles o'l dust which might otherwisegradually worlcinto the hearings are prevented from doing by the gas at12, which is received by the recess 13 in the peripheral flange letandtherccess 1.) in the sandbox 7; the two recesses'holding thegasket mo*ably in place when the whole is assembled. Now, oil or greasemay hesupplied to the cavity 16,

"andthis lulnicant working back through the hub lubrihates the bearingsurfaces at It and pass ng onward must percolate absolutely i i'ticlesfrom.

li e i ilt llirl e the hell- 1111 big. 3 1 show my invention adapted tothe present sleeve wherein the sand-box must serve to retain the sleeve(and with it the hub) upon the axle. In this case I show the space aboutthe peripheral flange 6, the gasket 12 almost wholly received by therecess 15, and the peripheral flange 6 in contact with the front wall1.8 of the sandbox 'i' which holds the hub on the axle.

While this form may be used under some conditions it is not recommendedas the wearing surfaces are exposed to the grit. To prevent this I will.employ a loose periphe-al flange 1 4', Fig. 7, which may be I is obviousthat the peripheral flange 6 does lubrication may be employed.

not need to be in contact with the front "wall 18 of the sand-box tohold the wheel on the axle. The screw cap prevents grit from enteringthe outer end of the journal and as the peripheral flange does not bearagainst the front wall 18, this permits the space on both sides of theperipheral flange, giving greater passageway for grit.

In Fig. 1 I show my preferred form which is a combination of the formsshown in Figs. 3 and 2. In this caseI employ a pair of peripheralflanges 6 and 1 1 respectively, with a recess in the curved flange letto partly receive the gasket 12 and with the rear peripheral flange 6bearing against the shoulder 22, the gasket 12 being held in place bythe recesses 13 and respec- 'tively.

In use the gasket 1s placed over the axle or sleeve, as the case mayrequire; the hub is placed on the axle; the sand-box, being separated,is placed over the axle and the peripheral flanges of the sleeve, therecess in the sand-box naturally registering with the gasket; the U boltor other clamping means 23 applied and tightened, bringing the twosections of the sand-box in rigid contact with the axle.

No oiling device is shown as any means of Preference, however, is givento the use of grease placed in the cavity 16,which naturally works outthrough the gasket 12 as above explained.

It is obvious that the peripheral flanges may be constructed on thesleeve if desired. It is also obvious that the peripheral flanges maybeconstructed on the hub if desired. Various changes may be resorted towithin the scope of the invention without departing from the spiritthereof.

Having thus described my invention, I claim 1. The combination with ahub and axle of a sand-box, comprised of channeled sections, one of thesections having an orifice in the bottom thereof, said sections lmving arecess to accommodate a gasket, a gasket in said recess, and a U boltbinding the sections together upon the hub and axle.

2. The combination with a hub and axle, of a sand-box, comprised of apair of channeled sections, one of said sections having an orifice inthe bottom thereof, said sections having a recess to accommodate agasket, a gasket in said recess, a sleeve having a peripheral flange anda recess in the flange to register with and receive the above mentionedsections together about the sleeve and upon the axle.

3. The combination with an axle, of a sand-box, comprised of channeledsections, one of said sections having an orifice in the bottom thereof,said sections having an interior recess to accommodate agasket, a gasketin said recess, a sleeve having a pair of peripheral flanges, a recessin one of the flanges to register with and receive the above mentionedgasket, and means forbinding the sections together, rigidly about theaxle, and revolubly upon the flanges of the above mentioned sleeve.

4. The combination with an axle, of a sand-box, comprised of channeledsections, one of said sections having an orifice in the bottomthereof,said section having an interior recess to accommodate av gasket, agasket in said recess, a sleeve having a peripheral flange, a looseflange adapted to be attached to the sleeve and to register with thechanneled sections, a recess in the loose flange to register with andreceive the. above mentioned gasket, and a means for binding thesections together, rigidly about the axle, and revolubly upon the llanges.
